yea they were spawnable spawnpoints... it's like an invisible object that spawns, and it has spawnpoints attached to it.. very easy.. just like for ex; the LVCPs are... check in FH1 for germanbridgespawn and alliedbridgespawn or something like that... otherwise just make a copy of the spawning LVCPs and rename it to something else and remove all the geometries.
the object works like a pushcage in the sense that it bleeds critical hitpoints all the time, then respawns in 0seconds.. so when the americans cap the flag, the german spawnobject bleed to death and doesnt respawn, and the allied object spawns instead.
If you have FHTMOD installed, you can just grab the spawnobjects from there and use them.
